Cranes stretch their highest at Lagos’ “city in the ocean”

Six Comansa cranes have reached their full height helping a Nigerian contractor build the Azuri Peninsula residential complex in a new city taking shape on reclaimed land in Lagos, Nigeria.

The 244-apartment scheme is part of the ambitious Eko Atlantic business and residential project under construction on the artificial peninsula.

The State of Lagos and the Chagoury Group are leading the development, which gives Lagos 10 square kilometres of new land, formerly lost to the Atlantic Ocean, intended to accommodate a thriving new business hub.

Azuri Peninsula is being built at the leisure-oriented Marina District, one of ten planned districts in the scheme.

The six Comansa cranes belong to the fleet of the turnkey contractor ITB Nigeria FZE. The machines, all with flat-top design and maximum load capacity of 18 and 20 tonnes, are building Azuri Peninsula’s three towers, the tallest reaching 140m.

Distributing progress photographs shown here, Comansa said ITB used hydraulic jacking cages to jack the machines up as the buildings expanded upward. The cranes are now working around the clock at their maximum height, the tallest of which is 163.5m.

The cranes were equipped with a system that increases the hoisting speeds for light loads, which the contractor said increased productivity.

"Due to the height of the buildings, it has been essential to rely on cranes with high hoist speeds," said Paul Kattar, Tower Crane Manager at ITB Nigeria. "The work cycles of the Comansa cranes on site are very short, which increase its productivity, and helps us to also shorten work times."

The cranes are working 24 hours a day, lifting steel structures during the daytime and helping with the concrete works during the night.
